Abstract:

By referring to the service network architecture and interoperation scheme of VoWi-Fi under 4G, the differences of the service network architecture and interoperation scheme of VoWi-Fi under 5G were studied and analyzed.Under the current situation that the network and terminal industry chain didn’t support the interoperability between standalone (SA) and Wi-Fi, a workaround scheme for interoperation in the transitional period was proposed, and the terminal and network side configuration suggestions were given to realize the interoperation between VoWi-Fi and VoLTE based on 5G network to ensure that users were unaware.The feasibility of this scheme was verified by practical tests.It provides reference for the actual deployment of VoWi-Fi.

Key words: 5G, VoWi-Fi, VoNR, VoLTE, handover
